Re: What to do with a booming hive?!
Janet when was this video shot? That level of activity is not at all unusual for an Arataki Carniolan and in fact it's a small hive. My guess is if you shot the video recently the hive must have already swarmed a while back or you would either have to have more boxes on it or they would be bearding outside the hive in huge numbers.
If it's a recent video, winter is not far off. If you believe they are still bringing in plenty of nectar you could add another honey storage super, but pretty much what you should be focusing on is ensuring they have enough honey stored for the winter.
The hive will start reducing in population very soon and these kind of carniolans go through winter with a lot less bees than an avaerage italian hive. You must get your mite control done now or you will probably lose the hive during winter. And I'm not kidding I know those bees, treat, or lose it.
In spring, it will behave a bit different from this year when you installed the package. At first it will be very low on bee numbers. But provided you keep mite numbers low, once some nectar starts coming in, the population will explode very quickly and they will attempt to swarm. Monitor it often and give them plenty of room. They will need a lot more honey storage boxes than what you have on it at the moment, or you will force them to swarm.
Study swarm control methods and do everything in your power to stop them swarming next spring. Achieve that plus mite control, and you will get a good crop of honey.
